The practical takeaway: if your goal depends on a known, reliable systemic dose, injection offers more certainty
Why cysteine is the rate-limiting factor: The intracellular concentration of cysteine sits close to the Km value of GCL (0.1 to 0.3 mM), meaning the enzyme is operating near its saturation point under normal conditions

However, CF, PCD, and NCFB are rarer with incidences ranging from 1 in 20,000 for PCD, between 50 and 1,000 in 100,000 for NCFB, and around 160,000 individuals with CF worldwide (Nigro et al., 2024
